1 Claim. (01. 85-13) Our present invention generally relates to re-- ceptacles, and more particularly to a novel and improved construction for retaining a recep.-' tacle insert in a holder for the same.

5 Although receptacles of the. removable insert type, as goblets, have been known and used in the past, various disadvantages have been found/ to be inherent in them. Expensive, as well as complicated, devices have been employed to posi 1 tively retain the insert in the holderduring usage. Such devices have failed to be popular because of the failure to observe the fundamental rule that a removable insert must not, only be positively retained in the holder during usage, but

1 must be removable from the holder with "minimum manipulation by, and vexation to, the user. The ideal device for this type of receptacle not only provides positive retention of the insert in one simple movement, but permits separation of go the holder and insert in as simple a fashion.

Accordingly, it may be stated'that it 'is one of the main objects of. our present invention to provide a receptacle of the removable insert type wherein the insert is positioned into opera- 25 tive relation with the holder by the mere act of moving theinsert intov the holder, and the holder and insert being constructed in such a manner that the insert is positively retained in position under the-influence of three separate and dis- 30 tinct physical forces. Another important object of our invention is to provide a goblet of the removable insert type wherein the insert is positively retained in position in the holder by the'c'ombined action of 35 atmospheric pressure upon the insert, the pressure of the holder sides, and a groove coupling between the insert and the holder;' the insert being removable from the holder by means of the simple act of pulling the insert out of the holder.

, Another object of the invention is to provide a drinking receptacle comprising a receptacle insert and a holder, the holder being constructed of resilient material, and the. dimensions of the 45 insert being such as to act as a plunger, when inserted in the holder, and force the air out from between the insert and the holder whereby the insert is retained in position in the holder, when. in operative position, by the combined action of atmospheric pressure of the holderonthe latter.

- Still otherobjects of the invention are to improve generally the simplicity and emciency of receptacles'of the removable insert type, and,

more especially to provides receptacle of such 55 'a type which is not only reliable and durable in usage, but economically manufactured for the market.

The novel features which we believe to be characteristic of our invention are set forth in particularity in the appended claim. The invention itself, however, both as to its construotion and usage, will best be understood by refer- 'ence to the following description taken in conreceptacle embodying ourinvention,

Fig. 2 is a plan view of the receptacle,

Fig. 3 is a quarter sectional view taken along line 3-3 in Fig. 2, the section being through the insert and bolderwalls,

Fig. 4 isa magnified detail view ofthe mechanical coupling between the holder. lip and the groove in the outer face of the insert.

Referring now to the accompanying drawing.v wherein like reference. characters in the' different figures indicate the same structural elements, the receptacle in Fig.1 is shown as comprising two portions. The insert I is preferably. fabricated of glass, although it is to be clearly understood that it may be composed of any other type of rigid material other than glass. Such.

materials may comprise phenolic condensation products, hard rubber or the like; The insert may be of colored, transparent, translucent or opaque material- The holder '2 comprises an upright, or support section 3 and a convex, or flaring, insert-hold ng section 4. The section I, as well as the support section I, are integral, and are. preferably composed of a metallic material such as chromium plated steel or brass. The section 4 may, if desired, be threadedly connected: to the upright section 3.

The insert-holding section 4 is fabricated from a relatively thin sheet of metallic material into the configuration shown. -It is to be understood that the relative dimensions of the section .4 and insert I in Fig. 3 are exaggerated and distorted in order to. illustrate the manner of.constructing the device. Fig. 4 shows more definitely the relative dimensions of the section I and insert I, and from this figure it will be noted that the section 4 possesses resiliency due to the relatively thin sheet fabrication thereof. The

configuration of the section 4 conforms to that of the lower half ef insertl.

The circular rim, of lip. portion of section 4 is bent. inwardly. This is clearly shown in Fig.1,

I and the numeral 4' designates the inwardly bent rim of the section 4. In the position shown in Figs. 1 and 3, the operative position of the receptacle, there exists a slight space 5 between the outer face of insert I and the inner surface of section 4. By way of example it is pointed out that space 5 be of the order of less than one quarter of an inch. The space 5' should be dimensioned with regard to the thickness of the plate from which section 4 is fabricated, and-the relative dimensions of insert I and section 4. The function of space 5 is to provide a vacuous space between elements I and 4 when the insert has been pushed into operative position in the manner of a plunger. Due to the inherent resiliency of the sheet, or plate, from whichsection '4 is fabricated, the base of insert I will act in the manner of a plunger and force the air -out from between the approaching faces of the insert andiinsert-holder section 4.

Of course, the base portion of insert I may be in contact with the base portion of section 4 in the operative, assembled position of' the receptacle. In that case the space between the flaring walls of the nested sections would be substantially evacuated. It will now be seen that the space 5 should be so designed that the evacuation thereof is completed bythe simple motion of pushing the insert I into the well, or section, 4. Thus, the atmospheric pressure upon the inner face of insert I operates to maintain the latter in assembled position.

A secondforce which is utilized to retain the insert in assembled position is the inward, and radially acting, pressure of the rim portion .4.

As explained before this is due to the inherent resiliencyof the material from which section 4 is fabricated. When the insert I is not in nested position, the flaring walls and rim 4 are restored to original position. In other words, when the insert I is pushed into nested position this results in distortion of the rim portion 4 in a direction away from the vertical axis of the receptacle. Due to this outward flexure of the section 4 the rim portion 4' exerts a radially acting pressure on the medial portion of insert I.

A third force that is utilized to maintain the insert I in nested position is provided by the cooperation between the rim portion 4-' anda circular recess 6. The latter recess, or groove, is provided in the outer face of the flaring walls of insert I, and" is placed at the circle of contact betweenthe rim edge and the inserts outer face. The groove 6 has its lower edge I rounded oil so that when the insert l is desired to be removed, the edge of rim portion 4' will readily, and'smoothly, ride downwardly over the edge 1. Those skilled in the art of fabricating receptacles, and particularly those or glass, are fully aware of the manner of providing the groove 6 in the outerface of the insert I.

The depth of recess, or groove, '8 is subject to variation. It need not be pronounced, and

may be of the order of magnitude of the edge during usage.

of rim portion 4'. It will now be seen that when the insert I is in nested position, it is not only maintained in such position by the conjointly acting forces of atmospheric pressure and the radially directed pressure of the walls of section 4, but the insert I is positively locked against tilting motion, as well as accidental withdrawal motion, by the rim edge-groove coupling.

It will also be clear that these three forces, although physically independent, nevertheless cooperate to produce the unitary result of positively maintaining the insert I in nested, or assembled, position as .shown in Fig. 1. When it is desired to disassemble the. receptacle, it is only necessary to pull the insert I upwardly, and this upward pull on the insert breaks the vacuum in space 5, pushes the walls of rim portion of the section 4 upwardly, and breaks the coupling between rim portion 4' and groove 5. It will be noted that this is all accomplished by one single motion, and that this motion is the exact reverse of the motion which causes assembly of the receptacle,

It is to be understood that the magnitudes of the groove 6, the plate of section 4 and the space 5 are wholly. within the discretion of the designer of the receptacle. What is essential is that these various dimensions be chosen to accomplish the functions stated hereinbefore.

While we have indicated 'and described one preferred construction for carrying our invention into effect, it will be apparent to those pended claim. 1

What we claim is: In combination, in a receptacle of the removable insert type, a holder section formed of a relatively thin metallic plate into an insert,

holder, the latter having resilient flaring walls and an inwardly bent rimportion, a glass in- .sert receptacle nested within said holder and having its nested portion similar in configura- -tion to that of the holder, the walls of the in:

sert and holder being spaced apart by a relatively small distance which is suflicient to provide a substantially evacuated space between the walls of the insert and holder when the former is in nested position, said Insert being retained in .nested position by the conjoint action of atmospheric pressure on the insert and the radially directed pressure of the holder walls, a sub- .stantial portion of the insert extending above the holder-rim, a groove provided in the outer face of the insert at the line of contact between the holder rim gedge and the external face of the insert, and said rim edge being disposed in the groove to prevent tilting motionof the insert- JACOB HELLER.
